' vent any liquid from entering the empty bottle.

Other objects will appear as the disclosure progresses. The drawings areintended mere ly to indicate a possible embodiment of the invention itis therefore not intended to limit the invention to the embodimentillustrated but rather to define such limits in the appended claims.

For a more general understanding of the invention attention is 110wcalled to the drawings in which a preferred embodiment is shownillustrated.

Fig. 1 is across section of a. neck of a bottle showing the deviceattached therein.

Fig. 2 is a. section on line 22 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a section on line H of Fig. 1.

Fig. 5 is a section on line 55 of Fig. 1.

Fig. 6 is a section on line 66 of Fig. 1.

Fig. 7 is a front view of the plug.

Fig. 8 is a view of the cup partly in section.

Fig. 9 is a perspective view of the valve.

Referring now to the drawings in detail. in which like referencecharacters denote like parts throughout the specification numeral 1represents the neck of a bottle in which is placed the non-refillabledevice consisting of a cup 2 wedged in place by a sleeve 3 made of corkor a like material. Fastened within this sleeve at the top is a plug atand loosely resting at the bottom of the cup is a valve 5.

' The plug is provided with three vertical slots, numeral 6 at the neckthereof and three flattened portions numeral 7 at the crown thereof.Means are provided to lock the cup and plug together which consists ofslot 8 formed in the neck of'the plug and adapted to co act with a setof three lugs numeral 9 I formed in the cup 3. I

hen inserting the plug 4 within-the cup, the plug is first positioned sothe slots 6 will register with the lugs 9 of the cup, the plug 7 is thenpushed inwardly of the cup and then given a twist so the lugs 9 willrest in the slot 8 midway of the vertical slots 6 as shown in Fig. 4.

In practice the entire unit is assembled with. the parts in relativeposition and then forced in by a suitable tool in the neck of thebottle, the bottle of course first being filled wit-h the liquid.

lVhen the bottle is inverted for the purpose ATTE'N'T OFFICE.

of emptying its contents the valve 5 will move away from the hole 10 inthe bottom. of the cup 2 andallow the liquid to pass through thevertical slots 6 and by the flattened portions 7 of the plug and thenceout from the bottle neck opening. As will be seen from Fig. 1 it will beimpossible to normally fill the bottle when once emptied as the valve 5will act as a check and thus prevent the liquid from passing through thehole 10 into the bottle.

Having thus described. my invention, I

I claim 1. In a deviceof the class described, the combination of abottle neck, a resilient. sleeve inserted in said bottle neck, a cupsupported by said sleeve, a plug in said cup, means for holding the plugin place, said means consisting of a set of three indentations formed inthe wall of the cup and adapted to coact with a slot formed in the neckof the plug for locking the said cup and plug together, a valve restingin the bottom of the said cup above an opening therein, a series ofvertical slots in the neck of said plug and a series of flattenedportions in the crown of said plug, said valve when the bottle is tiltedadapted to admit liquid through said hole in the bottom of'the cup andthence to the vertical slots and said flattened portions, and thence tothe neck opening of the bottle. said valve when the bottle is in itsupright'position adapted to prevent any liquid from entering the bottle.

2. In a device of the class described, the combination of a bottle neck,a resilient sleeve inserted in said bottle neck, a flanged cup supportedwithin said sleeve, a plug in said cup,

means for holding said plug in place, said means consisting of a set ofthree indentations plug together, a valve resting in the bottom of saidcup above an opening therein, a se ries of vertical slots formed in theneck of said plug, the depth of said Vertical slots being greater thanthe depth of the first Inen tioned. slot, and *2FS81l8S of flattenedportions in the crown of saidplug, said valve when the bottle is tiltedadapted to admit liquid through said hole in the bot-tom of thecup andthence to the vertical slots and said flattened portions, and thence tothe neck open ing of the bottle, said valve when the bottle isinitszupright positionedapted to prevent anyliquid'fromfenteringthebottle; t In testimony whereof I aflix my signature. FREDERICK WESTPHAL.
